8 Claims.

This invention pertains to broilers and in referring to the invention bythis designation I have reference to the entire broiling oven orcompartment of a cooking range and more particularly to that type ofcooking range the broiling oven of which is provided with gaseous fueltype burners.

One of the primary objects of the invention is to provide a cookingrange of a broiler having top and bottom broiler burners.

Another object of the invention is to provide a broiler grid or panwhich can be raised and lowered in respect to the upper broiler burnerbut remains in the same position with respect to the lower broilerburners by reason of the fact that the lower burners are elevated andlowered as a unit with the broiler grid or pan.

Another and still further object ofthe invention is to provide a novelflue arrangement for disposing of the hot products of combustion andgases of the lower broiler burners.

Other specic objects and novel features of construction which areincidental to a broiler having the foregoing enumerated attributes willappear from thefollowing description when read in the light of theaccompanying drawings.

In the drawings:

Fig. 1 is a vertical sectional view, from front to back, through abroiler which embodies the present improved invention.

Fig. 2 is a vertical sectional view taken at right angles to Fig. 1 ofthe drawings.

Fig. 3 is a vertical sectional view transverse a broiler embodying amodified form of the invention.

Throughout the following description the word broiler is utilized todesignate the entire broiling oven or chamber and the parts making up acomplete broiling apparatus. In the description that member or elementwhich is used as a support or carrier for the food or the utensilcontaining the food to be broiled or otherwise cooked is referred to aseither a grid or pan It is to be understood that the present broiler canbe incorporated into and used in conjunction with cooking stoves orranges of widely varying design and construction and that although thebroiler burners are described as gas burners the burners could beequally well operated by or upon some other specic type of fuel.

With the foregoing in mind and having reference to Figures 1 and 2 ofthe drawings I have here illustrated a gas range which in its bottom orbase is provided with an enclosed housing A and uponwhich issuperimposed `a broiling cham- 55 ber or oven'B whichA in turn supports`a cooking or so-called baking oven C provided at its top and rear endwith a conventional outlet flue l.

The broiling and baking ovens are preferably inset from the front of thelower compartment or housing A to provide a horizontally disposed tabletop-like working surface 2 which extends across the entire width of thefront of the range in a horizontal plane at a convenient height abovetherloor of the room in which the range is positioned.

The baking oven, at its front end, is provided with a conventional door3 having an `operating handle 4.

The broiling chamber throughout a large portion of its height is open atits front end as appears at 5. This opening extends from the tabletop-likeworking surface 2 upwardly to the lower end of a transverselyextending closure panel 6 the up-per end of whichterminates at oradjacent the lower edge of the baking oven door 3.

By reference to Figure 2 of the drawings it will clearly appear that thebroiling and baking ovens are in a common chamber or housing the outerside walls of which are I and 8, a rear outer wall 9 and a top wall lil.The front of this housing is dened by the range front frame Il, ovendoor 3 and the hereinbefore referred to panel 6. This common chamber hasno bottom for reasons which will hereinafter more clearly appear. Abottom closure, if used, would however have to be providedwith anopening permitting the passage of fuel pipes and the members whichinterconnect the broiler grid or pan with that portion of the elevatingmechanism which is within the lower housing A, as will hereinafter morefully appear.

Most ranges today are of the so-called fully insulated type and such arange is illustrated in the drawings with the result that the side, rearand top walls of the common chamber containing the broiling and bakingovens is of the double or spaced wall type with the space between thewalls filled with suitable insulating material l2.

The baking oven proper has its side walls I3 and I4 arranged in spacedparallel relationship to the inner side walls of the range while itsrear insulated wall i5 is arranged in spaced parallel relationship withthe inner rear wall of the range to provide flues or passageways I6 andI1 at each side of the oven and a similar iiue or passageway I3 at therear of the oven. The upper edges of the side and rear walls of the ovenstop considerably short of the under side of the range top. The. oven isprovided with a fully insulated bottom I9 which is disposed immediatelyabove the upper broiler burners which are designated as an entirety inFigure 1 of the drawings by D.

A fuel manifold chamber is provided behind the range front panel 6 andis defined by a rear wall 2| and a bottom wall 22. A fuel manifold pipe23 extends longitudinally of this chamber and is connected by a suitableconduit 24 to a main fuel supply pipe 25 positioned in the upper frontend of the lower range housing A.

The upper broiler burners are specifically illustrated as being in theform of a plurality of elongated burner arms 26 arranged in separatedparallel relationship. The front Aends of theseburners extend into thechamber 20 for suitable connection with the fuel manifold pipe 23 Whiletheir rear ends are removably and quickly detachably supported as at 2|Vupon a suitable bracket 28, The spaces between the burner armsthemselves and the spaces between the outermost burner arms and theinner side walls of the broiler chamber are closed to a substantialdegree by placing at each side of each burner arm an elongated radiantelement 29.

By reference to Fig. 1 of the drawings it will be seen that the commonhousing within which the broiling and baking ovens are located has alarge opening 30 into a lower housing or chamber A. The structure forsupporting and guiding the broiler grid or pan is positioned within thislower housing and will now be described in cornbination with the broilergrid and the iiue arrangement for the bottom broiler burners. Thebroiler grid or pan is designated as an entirety at E and is illustratedas comprising a grid 3| mounted on a carrier 32. The carrier supportingthe grid is supported at its front and rear upon suitable rollers 33which are positioned adjacent the front and rear ends of a pair ofguides or trackways 34 and 35 positioned in horizontal alignment atopposite sides of the broiling chamber and suitably secured, as bywelding, to the inner walls 36 and 3'! respectively of the flues F andG. It will be obvious that in accord with the wishes of the operator thegrid and a pan could be used in combination or that either of them couldbe used independently. When the grid alone is used it is necessary tomake provision for collection of meat juices and grease which would fallthrough the grid, and accordingly a grease collection pan 38 is disposedwithin the lower housing A beneath the open bottom 30 of the broilingchamber. This grease collection pan has an inclined bottom to providefor the total discharge of its contents through a suitable dischargepipe or valve 39. The grease collection pan would have to be emptiedperiodically into a suitable receptacle or a conduit from its outletopening 39 be provided to carry the grease to some suitable place ofdischarge or collection.

The ilues F and G have outer walls 40 and 4| respectively which are inseparated parallel relationship to the inner side walls of the range.Each of the flues extend upwardly within the broiling chamber and haveopen upper ends 42 which when the broiling grid or pan is in itslowermost position, as illustrated in Figure 2, eX- tends slightly intothe ueways i6 and at the opposite sides of the baking oven C. Thepositions of the upper open ends of the fines F and G when the broilergrid or pan is elevated to its uppermost position are illustrated indotted lines in Figure 2 of the dra-wings and in this ligure of thedrawings the elevated position of the broiler grid is likewiseillustrated in dotted lines.

Immediately beneath the broiling grid supporting runways 34 and 35 thenues F and G have their inner walls provided with elongated slot-likeopenings 43 which provide communication betweenthe flues and thebroiling chamber at a point beneath the broiling grid or pan and abovethe lower broiler burners which are designated as an entirety at H. Thebroiler burners H need not be of any specific form but in the presentembodiment of the invention each of these burners is illustrated asbeing in the form of an elongated burner housing which is of a lengthsubstantially equal to the depth of the broiling chamber and is of theso-called cross re type. That is to say, each of the burners is providedwith two rows of burner orifices or ports with the ports of each rowdisposed at an inclination to the ports of the other row so as to causea cross re or cross flame as is clearly illustrated at 44 in Figure 2 ofthe drawings. Each of these burners is suitably secured as by a bracketor brackets 45 to the inner wall of one of the flues F and G and isdisposed slightly below the opening 43 in the inner wall of the flue. Toassist in directing the hot products of combustion generated by thelower broiler burners into the ues F and G baiile plates 46 are providedand are suitably secured as at 4l to the under side of the trackways 34and 35 and extend inwardly and downwardly at an inclination to overhangthe burners H and deflect the hot products of combustion into theopenings 43 at the lower end of the fiues F and G and protect the burnerfrom dripping grease.

Inasmuch as the lower broiler burners H move upwardly and downwardlywith the broiling grid or pan and flues F and G, as will appear from thefollowing description, these burners are provided with flexible fuelconduits 48 which have connection with the aforementioned main fuelsupply manifold 25. A series of gas cocks 49 are positioned exteriorlyof the front of the upper end of the lower housing A for controlling thesupply of fuel to the several burners whereby any one or more of themcan be operated as desired. In the present arrangement four gas cocksare illustrated and provision is made for controlling the supply of fuelindividually to the two lower broiler burners and individually to thetwo upper broiler burners. This arrangement will require that the twoupper broiler burners at the left have a common manifold or be in theform of a joint burner and the two upper broiler burners at the right besimilarly constructed. It will be obvious that should it be founddesirable each of the upper broiler burners could be an individualburner and that additional gas cocks would provide individual control ofthe supply of fuel to each of them.

A pair of triangular shaped plates 5U have their upper ends secured tothe flues F and G respectively while their lower ends extend downwardlyinto the lower housing A. A vertically disposed arm 5| is secured toeach of these plates and extends downwardly below the lower end thereof.By reference to Figure 2 of the drawings it will be seen that theseplates and arms closely parallel the side walls of the housing A. A pairof cross arms 52 and 53 arranged in separated and parallel relationshipare pivotally connected as at 54 and 55 respectively to each of thevertical arms 5|. The lower cross arms 53 have their outer endspivotally connected as at 56 to the lower housing at a point adjacentits front while the upper arms 52 have their outer ends -pivotallysupported on a horizontally disposed and transversely extending shaft lwhich is supported in suitable bearings 58 positioned at each side ofthe lower housing A adjacentv the front end thereof. A cross brace 59interconnects the vertical arms 5I at a point closely adjacent theirlower ends. A pair of coil springs 60 have their inner and lower ends Elconnected to this cross arm while their upper and outer ends 5.2 areconnected to the transversely extending shaft 51. These springs tendnormally to exert an elevating force upon the broiling grid or pan andthe ues F and G with the result that these members can be raised andlowered with the minimum of effort. The springs overcome to a largedegree the inclination of these members to .drop with the result thatthe parts can be lowered without the operator expending any great amountof effort to prevent their lowering too rapidly.

To provide a convenient means for raising and lowering the broiling gridand its associated flues I have provided exteriorly of the broilingchamber and at the front thereof a handle 63 which is reciprocablymounted upon an arm 64 which has attachment to the broiler grid or pansupporting runway 34. The arm 64 passes through a housing 65 and thehandle 63 has an extension 6E into this housing. The handle extension,6E has locking engagement with the housing. This locking engagement isbroken by pushing the handle 63 inwardly and when the handle is in aninward position the broiling grid and pan together with its runway andall the associated parts can be raised and lowered. When the broilinggrid or pan is positioned as desired the operator permits the handle tomove outwardly so that its extension has locking engagement with thehousing S5 to maintain the parts in their set positions.

The operating handle 63 and its locking association wtih the housing (i5forms no specic part of the present invention and this construction isillustrated and described specifically in a copending application in thename of William H. Frick, Serial Number 324,707, filed March 18, 1940.In the present construction an operating handle and a means for lockingor securing the broiling grid or tray in a set position is a necessaryrequirement but the specific construction for effecting this result canbe widely varied without in any way departing from the spirit of theinvention which is the subject matter of the hereinafter appendedclaims.

The present broiler provides an arrangement whereby food placed upon orin the broiling grid kor pan can be optionally simultaneously cookedfrom above and below or from above only or from below only. Thearrangement is further such that the broiling grid or pan lcan beconveniently elevated or lowered in respect to the vupper broilingburners which will facilitate cooking operations, as will be readilyapparent to `those skilled in and familiar with cooking. The arrangementalso assures that the bottom broiling burners are at all times correctlypositioned for underneath or bottom cooking irrespective of theparticular position in which the broiling grid lor pan may be set.

In a broiler having top and bottom burners provision must be made toprevent the bottom burners from interfering with the operation of thetop burners which is a result which would occur were the products ofcombustion of the bottom burners permitted to reach the upper burners.

ent nues for the bottom burners are provided. These bottom burners Ventthrough the vertical ues F and G into the iiueways I6 and I1 at thesides of the baking oven and from there pass upwardly and over thebaking oyen to discharge through the main flue outlet I. The upperburners Vent through the spaces or iiueways $7 between the flues F and Gand the adjacent side walls of the baking oven. The upper broilerburners are used also for the purpose of heating the baking chamber andto prevent localized overheating of the bottom of the baking chamber aninsulator or heat deiiector 68 is provided at the under side of theoven.

Whenever it is desired to conveniently visually inspect the articlebeing cooked on the broiling grid the grid is pulled outwardly from thebroiling oven and to facilitate this movement the front edge of the gridor tray is provided with a handle 69 which extends outwardly through theopen front end of the broiling chamber to a point where it can beconveniently grasped. This handle is sufciently remote from the interiorof the broiling chamber to prevent it from becoming too hot to begrasped. When the broiling grid and pan are pulled outwardly from thebroiling chamber venting of the lower broiler burners into the iiues Fand G, by reason of the baiiles 46, is sufliciently complete to. preventthe lower broiler burners from interfering with the operation of theupper broiler burners notwithstanding the fact that the broiling tray 32in this instance would be no longer interposed between the upper andlower broiler burners.

When a combined broiling grid and pan are yused the pan can serve as thecollection medium for meat juices and grease unless it be desired toprovide the pan with openings in its bottom which would drain into thegrease collection pan 38 in the lower housing A. When a grid alone isused the grease collection tray 38 is an essential V.element asotherwise it would be impossible to keep the base chamber A clean.

When aA grid type food and utensil supporting element is used alone theventing arrangement for the lower burners is such as to prevent theoperation of the lower burners interfering wit-h the operation of theupper broiler burners.

In Figure 3 of the drawings a modified form of Ithe invention isillustrated. The construction of the modified form of the invention isidentical with that of the preferred form with the exception of the typeand construction of the lower broiler burners` Accordingly the samereference numerals appearing in Figures 1 and 2 of the drawings are usedin respect to Figure 3 with the exception of the lower broiler burners.

Thelower broiler burners in this instance are designated as an entiretyat J and are commonly referred to as radiant type burners. Specificallythey each comprise elongated burner housings 'l0 provided in their topwalls with burner ports or orices which discharge fuel within suitableradiant elements 1l which are supported upon the burner housings. Theseradiant elements can be of varying constructions. In the presentinstance they are vertically elongated and terminate immediately belowthe inlet passageways 3 into the lower ends of the flues F and G.

In this figure the broiling grid and pan are shown as being completelyremoved from their supporting guides or runways 34 and 35 but it is tobe understood that a suitable food and utensil supporting element isprovided and Supported for sliding in a horizontal plane upon the runwayrollers `33.

The modified form of the invention has all the attributes of thepreferred form of the invention and its operation is similar. Figure 3of the drawings is for the purpose of illustrating the use of theinvention in broiling ovens having burners of varying construction. Thedrawings and foregoing description are to be considered as merelyillustrative of the inventive concept and the invention is to be limitedonly within the scope of the hereinafter appended and following claims.
